First of all, understand what hacktivism is. “Hacktivism is the subversive use of computers and computer networks to promote a political agenda. With roots in hacker culture and hacker ethics, its ends are often related to the free speech, human rights, or freedom of information movements,” as explained in Wikipedia. The motivation behind Dedsec is hacktivism, thus Dedsec is actually a hacker group that is trying to achieve a social objective.

This is also true to the main characters of the game. Gone are the days where a hacker just sits in a basement in front of his computer. What we have right now are modern hackers. The developers have researched on this from actual hackers of this era.
